WitrynaAdsorption is the simplest and the oldest method of immobilizing an enzyme onto a water-insoluble carrier. It has already been mentioned (p. 18) that as early as 1916 Nelson and Griffin observed that invertase adsorbed on active charcoal retained its sucrose-splitting activity. Since this discovery, the adsorption method has been … WitrynaThe immobilized biocatalysts were prepared as previously described using Octyl–SiO2, a silica-based hydrophobic support obtained from rice husks, an abundantly available agro-industrial waste. Its complete structural and textural characterization, as well as its use as support to prepare active
